How to treat anf prevent mold in JVC apartment closet?« Back to Previous Page

The damp smell and black spots indicate active mold growth, likely due to condensation forming on that outer wall. This is a common issue in JVC apartments, where exterior walls can become significantly colder than the humid indoor air, creating a perfect environment for mold.

For a small, visible area, you can clean it yourself. Wear an N95 mask and gloves. Mix a solution of one part white vinegar to four parts water, lightly scrub the affected wall surface and the bag, then wipe dry. Avoid bleach, as it only removes the color and doesn't address the root moisture issue. Discard any porous items like cardboard boxes that show signs of mold.

Prevention is critical in our climate. The most effective step is to improve air circulation in the closet. Leave the door slightly ajar and ensure stored items aren't pressed directly against the walls. A small, rechargeable dehumidifier or silica gel desiccant packs placed inside can help control the micro-climate. If the wall feels consistently cold, consider having a professional assess the insulation or check for any minor leaks from the AC condensation line.

If the smell persists or the spots return quickly after cleaning, the growth may be behind the wall or in the insulation. In such cases, a professional inspection with moisture meters and thermal imaging is recommended to identify the exact source of the condensation before it spreads.
